We present a localization technique for an optically trapped microparticle inside hollow-core photonic crystal fibers which is the basis of a new generation of fiber optical sensors. A polystyrene particle of diameter ~15 µm is optically trapped and moved inside the hollow-core fiber by optical forces while its position is tracked using coherent optical frequency domain reflectometry. We demonstrate that this technique can locate the particle position with a standard deviation of ~10 µm. By applying a time-apertured Fourier transform, the dynamics of particle motion can be resolved with millisecond temporal resolution. |
